imported ones split and pull apart, then please
consider these Graphite Coated JBM gaskets.
Made in USA and only $4 each
Gaskets for Rotax 447, 503, and 582 in stock.
Fuel Tank Grommets made from the same
rubber
as our Carb Sockets. Just grease them up
and push them into any 1/2 inch diameter hole in
your fuel tank. Grease your barb, and push it
through the grommet. (
JBM does not sell barbs.)
If you need to install a grommet in a plastic tank,
use a woodworking drill of the type shown. Be
sure there are no sharp edges.
$5 for set of 4 pieces
Carburetor Vacuum Plugs for unused primer ports.
These handy little things replace the easily rotted
and cracked original equipment. Useful on any
Bing or Mikuni carburetor.

Real RUBBER BOOTS for IGNITION WIRES. Fits
both cap and coil ends. In many areas of the country
these little boots age crack and rot very quickly. These
hand made replacements are made from the same
rubber as our carburetor sockets.
Replacement is easy:  Just remove the ignition wire
from cap or coil by unscrewing the wire. It fits on a
threaded "nail".
$12 for set of 8 boots

Testimonials from Challenger web site blog:
I replaced my first set of Rotax carb sockets and throttle/enrichener cable
boots at 200 hours. They were starting to get cracks on the outside. I
replaced them with JBM sockets and boots and have a little over 200 hours on
them. They still look great--no cracks whatsoever.

Hi Mark. We built our Challengers at aboput the same time. I had the same
experiences with the carb boots and replaced them at about the same times.
The JBM's are still holding up fine with close to 500 hours.

Hi Flyers!
I feel kinda funny telling mostly guys about this (not a girly thing) but, I just wanted to
share an experience that I had today!
With the WX forecast OK, It was the day I'd set my goal & schedule to get out to
Sawyer's Airfield (my home field)
& look over any possible weather damage or neglected items I had not gotten around
to.
One such item was simply replacing the Rotax carb boots that connect the dual Bing
carbs, with the new JBM boots I had bought a few months ago.
They're made from a "superior blend" of rubber, and are reported to last much longer
than the Rotax ones.
My existing Rotax boots were still new looking with only a minor dullness and still
seemed to flex a little.
I've seen them on other Rotax equipped aircraft with an appearance more dull & dry
looking.
I'd read stories of carbs falling off, or high temps, etc.
Well, it wasn't ideal flying conditions with an 11 Knot 90* cross wind, and my broken
wrist still healing.
My friend Tony helped me replace the old boots with the new ones.
I explained to him why I felt spending a little extra money and replacing a known "weak
link" in the power plant was
beneficial for my peace of mind.  The old boots showed a few superficial hairline
cracks after he started distorting them.
He then squeezed one into an oval shape and "poit" it split wide open!
"Dang!! Looky There!!"
I had run the engine for 20 minutes a few hours earlier, but not above 3000 rpm.
One cylinders EGT temps a "skosh" higher than the other, but not anything that would
have given me a "no go"decision.
Anyway the point is, don't trust a simple visual inspection of parts that are getting  kinda
old but still look "fair"!
I'm sure I could apply that to other things too, but we'll just let that go for another
discussion!
I look forward to getting to fly again soon!
Have a good one!
